I'm not totally, totally sold on Microsoft's vista yet, but I have to say that, despite the eye candy and despite the wierd way in which some things happen (disappearing 'recently-used' app shortcuts, anyone?), some of its technology does make things easier. The file indexing got turned back on and, after its initial hammering of my disk, seems to have settled down and made things faster and better. The way I can plug in almost any device and the drivers get installed invisibly and automatically is wonderful. And innovations like ReadyBoost, using a USB flash drive as a fast 'disk cache' help on my laptop to keep the main RAM running smoothly.
The biggest surprise was that all my applications from my XP era have installed and worked well, with only a very few minor problems.
It's still early days, but the tipping point is upon me and I suspect it'll be Vista most of the way home from here.
